2. Ripple marks - Wikipedia

   en.wikipedia.org/wiki/Ripple_marks

   Like the sinuous ripples, this form of ripple is created by unidirectional flow with the dip at an angle to the flow as well as downstream. Linguoid / Lunate Linguoid ripples have lee slope surfaces that are curved generating a laminae similar to caternary and sinuous ripples. Linguoid ripples generate an angle to the flow as well as downstream.

3. Wave-formed ripple - Wikipedia

   en.wikipedia.org/wiki/Wave-formed_ripple

   Symmetrical ripple. Although symmetrical ripples are also called bi-directional ripples there is a difference between them. Bi-directional ripples are rarely symmetrical due to the difference in force of the two directions, where as the wave formed or oscillation ripples form from the circular water movement pattern of water molecules.

4. Aeolian landform - Wikipedia

   en.wikipedia.org/wiki/Aeolian_landform

   Ripple marks: Ripple marks are small ridges of sediment that form due to wind or water blowing over loose sediment in either a current or wave pattern. Aeolian ripples result from high velocity winds which form fine, well-sorted grain particles into long, flat, asymmetrical ripples. [citation needed]

5. Sedimentary structures - Wikipedia

   en.wikipedia.org/wiki/Sedimentary_structures

   Asymmetrical ripple marks These are created by a one way current, for example in a river, or the wind in a desert. This creates ripple marks with still pointed crests and rounded troughs, but which are inclined more strongly in the direction of the current. For this reason, they can be used as palaeocurrent indicators.

6. Giant current ripples - Wikipedia

   en.wikipedia.org/wiki/Giant_current_ripples

   Giant current ripples (GCRs), also known as giant gravel bars or giant gravel dunes, [1] are a form of subaqueous dune. They are active channel topographic forms up to 20 m high, which occur within near- thalweg areas of the main outflow routes created by glacial lake outburst floods . [ 2 ]
